XEROX DOCUPRINT 96/4635/180 IPS SYSTEM OVERVIEW GUIDE 1-5
IPDS data stream
All IPDS resources (print data sets, page definitions, form definitions,
page segments, fonts, and overlays) supported by the IBM 3825 and
3827 printers are supported by the Xerox IPS software. Additionally,
there are several data towers supported within the AFP environment
which are fully supported by the IPS software, to a level supported by
the IBM 3825 and IBM 3827 printer capabilities:
• IM Image IMD1
• FOCA: Font Object Content Architecture
• MO:DCA-P: Mixed Object Document Content Architecture for
Presentation
• PTOCA PT1, PT2, and PT3: Presentation Text Object Content
Architecture
• IOCA: Image Object Content Architecture
• GOCA: Graphics Object Content Architecture
• BCOCA: Bar code Object Content Architecture
• OL1: Overlay One
• PS1: Page Segment One
• Line mode data streams
Each of the data objects follow the same object rule of containing
delimiting fields with structured fields describing each object.
Dual Mode
Xerox DocuPrint Dual Mode option enables both DocuPrint NPS and
IPS systems to coexist on the same Printer Controller (Sun
workstation). This allows the DocuPrint system to receive data
streams supported by NPS and IPS, including IPDS, PostScript
Levels 1 and 2, HP PCL5c, HP PCL5e, and ASCII.
Either of the following types of configurations may be used:
• The same Token Ring or Ethernet connection can be used for
both IPDS (IPS) and Postscript/PCL (NPS).
• Both a Token Ring card and an Ethernet card can reside in the
Sun workstation controller, with one being used for IPDS and
the other for PostScript/PCL.
• Bus and tag attachment through the HCU can be used for
IPDS, and Token Ring or Ethernet connection for the NPS.
When the DocuPrint system is in IPS mode, it can accept PostScript
and PCL data streams in the background; however, it can print these
jobs only after it is switched to NPS mode. However, when the
system is in NPS mode, it cannot accept IPDS data streams in the
background.
